BSDNow 096: Lost Technology


BSDNow 096 has the usual new links, even more BSDCan 2015 video links, and an interview with Jun Ebihara about some of NetBSD’s lesser-known architectures.

(I like trying to guess the interview subject from each week’s obscure title; I was going to guess RetroBSD…  which would make a good topic to explore.)

DragonFly 4.2.1 out


There’s a minor update for DragonFly 4.2 – this covers a problem with i915 support, so it’s worth upgrading if you have an Intel video chipset.

NYCBUG: Precision Time Protocol


NYCBUG is having a chronologically appropriate speaker: Steven Kreuzer, talking about the Precision Time Protocol.  It’s 6:45 PM (EDT) tonight, at the Stone Creek Bar & Lounge in New York City.

BSDTalk 254: pfSense, FreeNAS, Ken Worster


I’ll quote right from the summary for the 14-minute-long BSDTalk 254: “An interview with Ken Worster who is presenting on topics which include PFSense and FreeNAS in schools at the Technology Teacher ME conference in Bethel Maine.”

Your off-topic link of the week: you have about a week to pay $35 to not die when the Earth is destroyed on July 5th.  It’s the 18th time the world has almost ended, so it has to work out one of these times.

Can’t stop typing apm?


Sascha Wildner has been removing the no-longer-needed bits of i386 support in DragonFly.  One of the things going away is APM, the 32-bit power management superseded by acpiconf.  If you still type ‘apm’ out of habit, it’s aliased so you won’t be surprised.

Console scaling options


Now that DragonFly can (in most cases) offer video outside of X with KMS, not just text, more console options are possible.   By default, your accelerated console will scale to 80×25, but you can now tell it how many columns you want and it’ll automatically scale to fit your resolution.  Or you can turn it off.

Powerd pays attention


Thanks to Sepherosa Ziehau, powerd will now start the shutdown process if you are down to 2% battery on your DragonFly laptop.  It also will delay for 60 seconds if you just booted up and are desperately searching for a power cable.

DragonFly 4.0.6 image up

DragonFly 4.2 and 4.0.6 branched


The more eagle-eyed may have noticed a branching for DragonFly 4.2, and for DragonFly 4.0.6.  The 4.2 branch is currently only a release candidate, so don’t necessarily change over yet – it’s for testing, not release.  Note that packages for 4.2 are not yet built, so you’ll have to manually specify a package path to install with pkg on 4.2 – for now.. That won’t be the case for the actual release, of course.  DragonFly 4.3 users will have to specify PKG_PATH manually to use 4.2 images until new ones are built.  4.2 release candidate users will be fine.  (see comments for correction.)

The 4.0.6 release is mostly to get the recent OpenSSL update into a 4.0.x build.

I am working on image building for both.

Thinking about a 4k monitor?


Matthew Dillon’s already using a 4K monitor on DragonFly, and he’s written notes on the various performance tweaks that went with it.

Video memory defaults changed


The direct memory access reservation on DragonFly has been set to 128M.  It used to be 16, but anyone using a system for more than a text console would want the greater memory reservation.  It can be set back to 16M, which is useful probably if you are one of those text console users, or if you have a strangely underpowered video card.

Eventually everything goes SMP


Even sysctl accesses can be made to handle multiprocessor environments.  This can actually make a difference when you’ve got a lot of processors building a lot of software, as in all of dports.

Sudden buildkernel improvements


From IRC today:

“19:43 <@dillon> I’m bored at the moment. lemme try to speed up module builds

Buildkernel, depending on your processor count, now may have tripled in speed.

Accelerated video users, please try this


If you are using a DragonFly system with accelerated video, and you have noticed that you can’t return to a text console after exiting xorg – Sascha Wildner/Imre Vadasz have a branch for you to try.  Please do so if you have time and are on master; this is the last big item to fix before the next release.

More Hammer 2 improvements


Hammer 2 now uses LZ4 compression by default.  It also uses a new CRC algorithm that performs much better, and there’s numbers to prove it.  It helps iSCSI too.  When I say new, it appears to be from the 1980s?  I may be looking at the wrong place.

Recent dragonfly-master users: update


If you were running a version of DragonFly 4.1 (i.e. the master version, not release) built between the 20th and 25th, rebuild.  There’s a UFS bug introduced in that short timeframe.

If you are running 4.0.x release or built your version of DragonFly-master outside of that date range – you are unaffected.

Shut up ARP


Sepherosa Ziehau has introduced a new sysctl:

net.link.ether.inet.log_arp_creation_failure

Set this to zero and you won’t get endless ARP events from networks you aren’t on.  For example, I’m hooked up to a cable modem.  I only get a public routable IP address, but the network used for the cable modem network itself bleeds ARP packets out where my DragonFly machine can see it.  Since it’s on a different network segment than the address I receive through DHCP, it always fails and the system logs it.  For example:

May 11 05:20:52 www kernel: arplookup 100.68.112.145 failed: host is not on local network

I can’t do much about it since that layer 2 leakiness is going to happen, but I can shut it up with this sysctl – and thank goodness, cause I’ve been seeing these messages since first using a DOCSIS modem in… 2001 or so?

Building only one compiler


DragonFly builds two compilers by default.  If you weren’t interesting in building both, there were switches to build only the default, like NO_GCC47.  This changed with every compiler update.

With the switch to GCC 5, the new switch is “NO_ALTCOMPILER”.  That will last through compiler changes.  I’m mentioning this now because sooner or later, you’ll want to gain back some time on a buildworld.

GCC 5 released, switched


DragonFly now has GCC 5.1 release.  If you are running DragonFly master (i.e. 4.1), you’ll probably want to both rebuild world and kernel, and update your packages so they all match.  There’s already packages built with GCC 5.1, so binary package upgrades can happen quickly.  There’s GCC 4.7 packages still available if you aren’t making the jump yet.

If you’re on DragonFly 4.0.x – nothing’s changed.
